Long Term Cosmetic and Functional Results of One Stage Reconstruction for Lower Eyelid Malignant Melanoma: A Single Centre Experience of Eleven Patients.

Introduction: Eyelid malignant melanoma represents less than 1 % of all skin melanomas and approximately 1 % of all malignant neoplasms of the eyelid skin. Because of its relative rarity, there is a paucity of descriptive papers reporting only small series of reconstructed patients. The repair of eyelid defects represents a reconstructive challenge. Ideally, the reconstruction of the defect must guarantee function with tissue of the same color, texture, and thickness of that of the removed skin and at the same time avoid complications such as ectropion and lagophthalmos.

Materials and Methods: We describe a consecutive series of 11 patients affected by cutaneous melanoma of the lower lid who underwent full-thickness excision of the neoplasm and subsequent wide excision. All the patients were treated in one-stage reconstruction modality with a modified monopedicle myocutaneous flap, harvested from omolateral upper eyelid, tunneled under the lateral canthus skin and armed with a conchal auricular cartilage framework. Four patients underwent the sentinel lymph node biopsy during reconstructive procedure. No major complications were reported. In our experience, the proposed myocutaneous flap allows to obtain excellent results, both aesthetically and functionally.

Conclusions: This technique has the advantage of avoiding multi-staged procedures, with respect for the oncological excision indication for head and neck melanoma, decreasing the incidence of associated major complications.
